This resource enables students to understand a technology that is such an integral part of our daily lives, yet little understood. It extends the information transfer lessons already on the NGSS Hub to computerized barcoding. Students will learn about encoding and decoding, then work in teams to design an improved information encoding system. Understanding the impact of engineering and technology on society is an integral outcome of these lessons. Strong cross-curricular connections are also present with the integration of informational text to support their understanding and grade appropriate application of standards for mathematics.
